First of all, what is WMI? WMI (Windows Management Architecture: Windows Management Instrument) is an implementation of Microsoft's Web-based Enterprise Management (WBEM) and Desktop Management Task Force (DMTF) industry standards. It is a standard-based system management development interface. This set of interfaces are used to control management computers. It provides a simple way to manage and control system resources. If you want to know more about him, you can refer to Micorosft Platform SDK. In this case, we just achieve a simple feature, Get relevant information about the hard drive in our system. We need to use the classes provided under the .NET FRAMWORK SYSTEM.MANAGEMENT name space.
Using system.management; using system.collections; using system.collections.specialize;
Namespace ace_console {class ace_console {[stathread] static void
Main
(String [] args) {StringCollection propNames = new StringCollection (); ManagementClass driveClass = new ManagementClass ( "Win32_DiskDrive"); PropertyDataCollection props = driveClass.Properties; foreach (PropertyData driveProperty in props) {propNames.Add (driveProperty.Name); }
int idx = 0; ManagementObjectCollection drives = driveClass.GetInstances (); foreach (ManagementObject drv in drives) {Console.WriteLine ( "Drive ({0}) Properties", idx 1); foreach (string strProp in propNames) {Console .Writeline ("Property: {0}, Value: {1}", Strprop, DRV [strprop]);}}}}}
The .NET Framework SDK comes with a logical hard disk size code:
[C #] using system;
Using system.management;
// this Example Demonstrate Getting Information About a class using the managementclass objectclass sample_managementClassClassClass Class
{
Public Static Int
Main
(String [] ARGS)
{
ManagementClass Diskclass = New ManagementClass ("Win32_LogicalDisk");
Diskclass.get ();
Console.writeline ("Logical Disk Class Has" DiskClass.Properties.count "Properties");
Return 0;
}
}
Imports system
Imports System.Management
// this Example Demonstrates Getting Information About a class using the managementclass
Class Sample_ManagementClassClassClassClass
Overloads Public Shared Function Main (args () as string AS Integer
DIM DISKCLASS AS New ManagementClass ("Win32_LogicalDisk")
Diskclass.get ()
Console.Writeline ("Logical Disk Class Has" & DiskClass.Properties.count.toString () & "Properties"))))
Return 0
END FUNCTION
END CLASS
